[dpdk-dev] ixgbe vPMD question

Hi, The recv function does a prefetch on cacheline1, however it seems to me that rx_pkts[pos] should be uninitialized pointer at that time: http://dpdk.org/browse/dpdk/tree/drivers/net/ixgbe/ixgbe_rxtx_vec.c#n287 So I guess it prefetches only random value. Or am I missing something? Regards,
